Afro/Net UNITED STATES PATENT v I THOMAS J'. LVITLE, JR.,OF PHILADELPHIA, PENNSYLVANI, A'SSIG'OH COMPANY, QF GLOUCESTER CITY, NEW JERSEY, A CORPORATIOX HIGH-POWER LAMP.'

To alliwhom 'it may concern:

Be it known that I, THOMAS J. LrrLr., Jr., a citizen of the United States, residing at the cit of Philadelphia, in the county oi Phila-l de phia andState of Pennsylvania, have invented certain new and useful Improvements in High-Power Lamps, oi which the following is a specification.

Objects of the present invention are, rst, to simplify and improve the construction and operation of high power lamps; second, to facilitate the starting of such lamps in such a way that even unskilled labor can be emloyed for this purpose; third, to provide reiable and eflicient workin parts for the lamp; and fourth, to provi e a high power lam suitable, for commercial purposes'and wor Other objects of the invention will appear from the following description and t e invention itself be nally c aimed.

Figure 1, is an elevational view of a lamp embodying features of the'invention. Fig. 2, is a view partly in section of one side of the upper portion of the lam Pig. 3, is a similar view of the other si e of the lamp. Fig. 4, is a detail view, principally in section, illustratin the upper vportion of the lamp. Figs. 5 an 6, are sectional views taken on the line 5-6, of Fig. 4, and illustrating two positions of the valve. Figs. 7 and 8, are respectivelyr a side elevation and a top or plan view of the pawl shown in Fig. 3, and Fig. 9, is a sectional view of the door shown in Fig. 3.

In the drawings 1, is a spider provided with depending rods or bolts 2, whichcarry the plate 3, which constitutes the top of the lantern proper and wnie-h is shown as provided with a curved rim that projects laterally. The displacer cylinder 4, is arranged so that its lower end projects through the plate 3, and its upper end is provided with an outward' flange which together with a gasket as of asbestos is clamped between the spider 1, and the upper head 5, which is bolted to the spider, thus the cylinder is well supported and is sufliciently free to ermit of its expansion and contraction un er temperature changes. The upper head carries the power cylinder dis lacer a..

9,'is a plate'with an upwardly(extending rim arranged beneath the spider It constitutes a 4base for the housing or casing 10,

which may be provided with openings thatadmit air to co the working parts.

11, is a casting bol-ted to the upperhea'd 5, and provided with a centrally arranged neck 12, which is connected with the valve casing 13. Within the casting 11, is arranged atfan chamber which may be covered as by a plate 14, held to place by screws 15, Fig. 3. Th`

fan chamber has a ldownward opening which communicates with the burner pipe 16, so

that a discharge is provided from it into the burner ipe. The plate 14, is provided with an inta e having a door 17, which can be more or. less opened so as to regulate the quantity of air admitted. This door is pivoted to a stud between the head of which and the door is interposed a spiral spring 18. This spring serves to hold the door in any position to which it has been adjusted and the construction as a whole is durable and we'll adapted to its puilpose. The casting'll, is

also provided with a gas'conduit 19, which does not communicate with the fan chamber but does communicate with the Aburner pipe 16. The arbor 20,iwhich carries the fan is journaled in the casting as is also the shaft 21.

22, are oil cups formed integral with or at' tached to the casting and they serve to lubricate the parts to which they are adjacent. Intcrposed between the displacer piston rod and a crank pin is a connecting'rod 23, one end of which is pivoted to a coupling 24, affording lateral motion in respect to the rod. The other end of this rod 23, isprovided with a fork pivoted to a sleeve 25', slidable on the crank pin. This construction compensates for irregularities in alinement and insures satisfactory operation.

26, is a wheel connected 'with the shaft 21, and itis provided with a crank pin 27, on

which is mounted a slidable sleeve to whichl is connected the forked end` of a connecting rod 28, and this connecting rod is connected with the piston of t-he working cylinder. The wheel 26, is peripherally grooved as is also a wheel connected ith the shaft- 20. A belt 29, consisting of a spirally wound wire passes around these wheels and runs in their 'ill grooves and it serves to transmit motion to the fan. This spirally coiled wire belt is capilot tube 31, having its lower` end arranged 'to light the burners to be presently described. As shown this pilot tube is arranged to support a continuous llame of which the size may be regulated by the screw 32.

33, is a heating burner supply pipe and it extends from the lower part of the valve cas ing downward and carries at its end a Bunsen burner 34, having an air inlet as at 35. This Bunsen burner 34, is provided and arranged for initially heating the lower end of the cylinder 4, before thel lighting burner 36, does so and in this way the engine is started. The

. valve casing is provided with a plug valve lighting or heating burners.

seat which is arranged at an inclination and -25 there is also an opening through it which accommodates the nut 37, that holds the plug valve 38. Gas is led to this valve by the port 39, Fig. 5, and from this valve gas is led to the burner pipe 19, by way of the port 40, and to the heating burner by way of the port 41. When the plug 38, is in the position shown in Fig. 5, no gas reaches either the As the plug isv turned in a clockwise direction, gas at rst reaches the heating burner 34, by way of the port 41, and the circumferential notch 42. By and by the notch gets out of line with the port 41, and the diametral opening 43, comes in line with the port 40, thus feeding gas to the lighting burner and extinguishing the heating burner.

The plug 38, is mounted upon the end of an operating rod 44, in such a way that the plug turns with the rod but has some motion in respect toit so as to compensate for anylack of perfect alinement. The lower end of the rod 44, passes through the plate 9, and baille 6, and is guided thereby. 45, is a. thumb nut forl turning the rod and of course the plug 38.- The motion of the rod is limited by the pin 46, which works between suitable stops 47 and 48, Fig. 3.v The operating rod 44, carries an adjustable couplinr 49, to which is pivoted a pawl 50. The pawl is fitted with a back stop 51, arranged to collide with the rod and with two skew teeth 52. The spring 53, may be employed for holding the pawl up to its work. The teeth 52, engage theteeth of a wheel 54, carried by the shaft 21, in a manner to be presently described. Assuming that the pilot light 31, is burning and that the op- I do not limit myself to t shown Fig. 5, and no gas passes through it.

The operating rod is then turneduntil the pawl 50, contacts with the teeth of the wheel 5 4, whereupon it is permitted to remain at".

rest for a -short time. Under' these `condi. tionsl gas passes by 41, to the heating burner pipe 33, so -that the heating burner 3 4, 1

ghted from the pilot light and its flame serves to warm the lower end of the cylinder 4, thus bringing the engine into condition for running as soon as 1t 1s started. The operating rod 44, 1s then turned further in the same direction with the result that the skew- Further motion of therod is checked by a r contact of the stops 46 and 48. This last mot-ion of the rod shifts the plug 38, into such position that the slipply of gas to the heating urner 34, is cut o while a supply of as is delivered by the port 43, to the lig ting burner and it then not only furnishes light by heating a mantle or mantles but a so driv'es the engine. To extinguish the light, the rod 44, is returned to its initial Josition. Upon the plate 3, may be arrange a sheet of asbestos or the like 55, and the rim of this plate is provided on one side with openings and on the other side with an upwardly in clined pin 56. The ring 57, is provided with hooks 58, which detachably take into the openings and it is also provided with a. loosely vriveted link adapted to engage and disengage the pin 56, so that the ring can be turned about the hooks as a hinge and the link can be made to engage and disengage the pin or the whole ring can be readily detached. The fact that the link'is loosely' riveted affords it suflieient movement and at the same time enables it to withstand the' The structure as a whole is suspended as for example from a gas pipe by means of a coupling formed as at 62 on the valve casing. It will be obvious to those skilled inthe art to which my invention appertainsthat modifications may be made in details without departing from the s in't thereof, hence llie precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings, but
